I am not saying I don't believe you, but as you said you have no data other than what Ted says. I respect his opinion and he may be correct. I am asking someone to show me.
I would never expect to make the same boost on a larger engine, that's the beauty of a larger engine is you don't have to. I also think too many people have been talked into running 9.7 or less compression on a larger engine and that will make you suffer with a smaller blower for sure. That's why I am looking at 10.5 CR for my build.
